Hardware Specifications

Rotor Dynamics and Probe Signal Integrity

The transducer utilizes eddy-current probe scaling to convert target proximity into a linear voltage signal. System accuracy depends on gap voltage validation, requiring a target of -10 VDC at the monitor input when at the designated electrical zero. Integrated coaxial shielding ensures cross-talk suppression, maintaining signal fidelity for high-speed vibration analysis and axial position monitoring.

Field Installation Guidelines

• Mechanical Installation

• Ensure a minimum of 5 full thread engagements when mounting the probe into the bracket.

• Use locking nuts to secure the probe position after achieving the target gap voltage.

• Electrical Termination

• Clean all coaxial connector interfaces with non-residue electronic cleaner before mating.

• Verify ClickLoc mechanism engagement to ensure 50 Ohm impedance continuity.

• Grounding

• The probe housing must maintain electrical continuity with the machine casing to complete the system ground path.

Frequently Asked Questions

• Can this probe be used as a standalone sensor?

  No. This probe is part of a tuned 3300 XL transducer system and must be coupled with the appropriate extension cable and Proximitor sensor.

• How is the probe gap verified?

  Monitor the DC gap voltage at the transducer monitor or BNC output, adjusting the probe depth until the -10 VDC target is achieved.

• Is the cable length field-adjustable?

  No. Cable lengths are factory-trimmed to maintain the 50 Ohm impedance characteristic. Modification will cause signal reflections and calibration errors.

• What environmental conditions can the probe withstand?

  The probe is rated for operation up to 177 deg C and is resistant to typical industrial fluids, provided the mounting seals are properly installed.

• Can the probe be hot-swapped?

  No. Disconnecting the probe while the system is operational will trigger a transducer fault in the monitoring system.

• Does probe misalignment affect data?

  Yes. Misalignment relative to the target surface center can introduce non-linearities and degrade vibration amplitude measurement accuracy.

• What is the frequency response?

  The system provides a linear frequency response from 0 Hz (static) to 10 kHz (dynamic).

• How should cables be routed?

  Cables must be routed through rigid or flexible metal conduit to prevent mechanical damage and exposure to electrical interference.
